Yeah.. you can just put the culture in the fridge at 4oC. Aspergillus sp. prefers warmer conditions to grow.. however by subjecting it to long term refridgeration may lead to altered growth states, eg, increased sporulation etc etc good luck....

The medical staff should observe their institution's procedures to protect both themselves and their patients from spread of infectious diseases. The use of such protective barriers as gloves, gowns, aprons, masks or protective eyewear can reduce the risk of exposure of the health care worker to potentially infective materials. All medical staff should take precautions to prevent injuries by needles, scalpels and other sharp instruments during procedures; when cleaning used instruments; and during disposal of used needles. Gloves should be changed after contact with each patient. Hands and other skin surfaces should be washed immediately after gloves are removed. When collecting blood, genital, tissue, cerebrospinal and other body fluid specimens universal cautions for the prevention of transmission of bloodborne pathogens should be followed.
